I'm a research student at the University of York in the UK. I'm studying
evolution in MDE.

I've recently been exploring the zoos hosted as part of the AM3 project.

I was wondering if there is a change history for some (or all) of the
zoos anywhere? I would be interested in exploring the ways in which
these transformations have changed in response to (1) changes to the
language in which they have been defined (e.g. KM3, Ecore, ATL), (2)
changes to the models that they instantiate / consume / produce.

If anyone knows of any such data, I would be very grateful to hear from you.
